Safari goodness?

I decided that when after getting my iPhone and making the upgrade to Leopard I would do away with Firefox. I had a couple of reasons for doing so.

1. Safari loads a lot faster than Firefox does
2. I can sync my Safari bookmarks with my iPhone
3. Less 3rd party apps to bog stuff down

So I took the jump and haven’t looked back, though I was missing the extensive plugins that Firefox had to offer, not to mention that I have a Linux machine at work that I am on way to much so its weird switching browsers. I have been able to over come the switching of browsers but have not been able to get back all the plugins I was using except for a few.
The main plugin that I was missing was AdBlock, I really don’t know how people can live with out it. After some Googling I came across Safari AdBlock which doesn’t work as well as the Firefox version but does a damn good job so I can deal with that. I also came across a really nice search addon which is much like Spotlight on OSX its called Inquisitor, so far that seems to be working really well right now. For the other Mac people out there what addons are you using in Safari if you are using it?
